# After a package has been built for all Debian/Ubuntu versions and
# platforms (typically using "da sbuildhack DSCFILE"), this script
# uploads the package into the release, proposed, or beta apt
# repository.  If -A is specified, only one architecture per
# Debian/Ubuntu version is uploaded.  If -S is specified, only the
# source package is uploaded.

# Upon completion, moves all of the generated files into the "built"
# subdirectory.

# This script will skip dists listed in ./nobuild.
